" Be it hownfthat` I, FRANK ONnnnva.

citizen of the United 'States of America, re-

siding at Toledo, Lucas County, Ohio, have o invented new and useful `Molten-Glass Charo Supplies, of which the following is arated 'asa eut-"od charge srplg for rotary table apparatus, as in bottle lowing machinos.

Referring to the drawings:

The fluidit of the'lmolte'ni glass, together with the equency of the steps of the intermittent travel of the table 'l0 or carrier gear 5 mayvdetermine thefquantity or volume of molten glass in each chargeY or cut oli portion. Further volume control is obtained in determining the cross-seetional area of the throat'14.

The gather or molten glass supply as a continuous low cut-oli a paratus, is herein disclosed as incorpora as a power actu' ated or automatic feature of .a ware forming machine. The power actuation and con- 8,9
